Nylon Fuel Bowl Screw Gasket 10-Pack

The Holley Nylon Fuel Bowl Screw Gasket 10-Pack (part number 108-98-10) is a direct-fit replacement consumable designed specifically for Holley carburetors. These nylon gaskets seal the fuel bowl drain and filler screws, preventing fuel leakage and maintaining proper carburetor operation across a wide range of engine builds and performance applications.

Each gasket measures 0.219 inches in inner diameter with a thickness of 0.063 inches—dimensions engineered to create a reliable seal under fuel pressure and temperature cycling. The nylon composition offers chemical resistance to ethanol-blend fuels and standard gasoline while maintaining flexibility across typical underhood temperature ranges.

The ten-pack quantity addresses both immediate replacement needs and provides spares for future carburetor service intervals, which is critical for enthusiasts maintaining multiple vehicles or frequently rebuilding carburetors during tuning work. Drivers restoring vintage Holley carburetors or performing routine maintenance should treat these gaskets as replaceable consumables to prevent fuel seepage and performance issues.
